Description of drawings
To help to understand better the present invention by reading the following explanation that provides with by way of example purely with reference to the accompanying drawings, wherein:
-Fig. 1 is the synoptic diagram according to cooling module of the present invention;
-Fig. 2 and 3 is views similar with Fig. 1, has wherein provided according to two kinds of different assemblies of the present invention.
Embodiment
Assembly 1 shown in Figure 1 is intended to cool off the band 2 that moves along direction shown in the arrow 4.This assembly especially uses under vacuum condition during the coating of for example band is handled.
Described assembly comprises:
-two are used to cylinder 8A and 8B that band 2 is turned to, and they are optional is furnished with motor-driven drive system (not shown);
-main cooling roller 10, it has an X-X and arranges towards divert cylinder 8A and 8B, thereby makes above-mentioned cylinder guide band 2 respectively by rights at the entrance and exit of roller 10;
-being used for band to be supported on roller 14 on the cooling roller 10, it has parallel with the axle X-X of roller 10 basically axle Z-Z, and preferably it is substantially perpendicular to the area arrangements that band moves around roller 10; With
-the second cooling roller 16, it has axle X '-X ' of the axle Z-Z that is parallel to roller 14, and arranges in contact that at that side and these rollers 14 relative with roller 10 common plane P is formed on the central plane of roller 10 and 16.
More accurately, in the time of on hot member being applied to the main cooling roller 10 and second cooling roller 16, they can be from the outside surface of the roller inboard row heat release energy to roller.For this reason, roller 10 and 16 comprises doubleshell (double casing) in known manner, and its permission cooling fluid for example cold water circulates at the interior periphery of these rollers.Also can imagine and use, the cooling roller of other type by contact cooling to known in those skilled in the art.
Supporting roll 14 itself is made of the single cylinder part with Z-Z or relevant or incoherent coaxial thin cylinder constitutes by a cover.Roller 14 is made by the material of elastically deformable, especially elastomer material.In the present invention, term " deformable material " is often referred to the material that its Young's modulus (or Young's modulus) is starkly lower than the Young's modulus of the material that forms band 2, and its reason will be explained below.The suitable elastomeric examples of material comprises the sulfurized silicone.
The material that constitutes supporting roll 14 also has preferred performance aspect heat conductance and the electric capacity, that is to say that it necessarily can not be fully or almost completely stop thermal conduction (for example as stupalith), have high conductivity traditional metal alloy but also needn't resemble.Further, it must store the heat energy that absorbs from band at its core.The elastomer material that constitutes supporting roll 14 has the thermal conductivity that for example is lower than about 1W/mK (every meter every Kelvin of watt) and the high heat capacity of for example about 1000J/kgK (the every Kelvin of joule per kilogram).
The diameter of roller 14 preferably the diameter of roller 10 1/4th and 1/10th between.In addition, the length of this roller 14 is at least less times greater than the width of band 2.
The operation of assembly 1 (having explained the method according to this invention) is as follows:
From the band 2 of the adjacent production assembly (as the roll coil of strip or heating component (not shown)) of assembly 1 upstream to be considered to the inlet that higher temperature arrives assembly 1, this temperature refers in particular in envrionment temperature and is higher than between the high temperature of the cleaved danger of the material that constitutes supporting roll 14, that is to say, for example between envrionment temperature and about 200 ℃.Can cause that it moves at least in part by cylinder 8A.
The low rigidity that forms the material of supporting roll has limited the danger that the band outside surface has cut, even also be like this when the parallelism problem occurring between a Z-Z and the X-X.In addition, band 2 has good cross section homogeneity.
In addition, be the thermal capacitance material owing to form the material of support roll 14, the portion of hot of described band is transmitted to support roll from band, thereby provides additional cooling for band.
The motion of band 2 drives support roll 14 around its axis rotation, and this roller 14 itself drives second cooling roller 16 again.The contact area that remains between supporting roll 14 and the roller 16 allows heat to be transmitted to the inboard of roller 16 from the peripheral portion of roller 14.Because forming the material of supporting roll is the high heat capacity material, therefore the heat that is transmitted to support roll 14 from band was stored in the periphery of roller 14 before it is transmitted to cooling roller 16.
Guaranteed under the insufficient situation of parallelism (parallelism) between axle Z-Z and the X '-X ' even form the elasticity of the material of support roll 14, between the outside surface of roller 14 and roller 16, formed big surface in contact high-caliber thermal conductance long-pending and that therefore have.
In the exit of roller 10, band 2 rotates and rotates and leave assembly 1 to cylinder 8B.
Therefore, the method according to this invention allows band 2 to be cooled with controllable mode, and does not damage or scratch its surface.The cooling that is obtained is all rapidly even, therefore both guaranteed institute's refrigerative band character evenly, shortened the length of refrigerative time and The corresponding area again.
It is not very complicated utilizing elastomer material to form support roll 14, makes second cooling roller 16 then based on existing technology.In addition, can advantageously utilize the circulation networking of the cooling fluid that is sent to main cooling roller 10, for example utilize the branch road of supply second cooling roller 16, that is to say, based on existing already present refrigerating unit, therefore minimum according to the investment cost of assembly provided by the present invention.
Fig. 2 has shown the variant of the assembly 1 that is different among Fig. 1, on the one hand, wherein replaces a support roll that two support rolls 14 are arranged between the main cooling roller 10 and second cooling roller 16; On the other hand, outlet turning cylinder 8B for example is similar to second main cooling drum 12 replacements of roller 10.The operation of this assembly is substantially similar to the operation of assembly 1 among Fig. 1.
According to the Application Example of the method for prior art and the Application Example of the method according to this invention of utilizing the assembly 1 among Fig. 2 in following detailed description.In two tables below, announced the operating parameters of this assembly:

When the first main cooling roller 10 and two supporting rolls 14 link, find that the cooling efficiency on the first main cooling roller 10 increases 15 times, and the cooling efficiency on second cooling roller 12 increases significantly also.This presentation of results support roll 14 provides high-caliber cross section uniformity coefficient for band 2, allows on the whole width of band high level and cools off equably.Utilize the temperature survey of infrared thermography to confirm that further cooling temperature is uniform.
In addition, consider the temperature that is reached by support roll 14, what may determine is, the material outer layer of roller 14 in predetermined period of contact, can be in the short relatively time local temperature that reaches with the contacted band 2 of these rollers.Especially when the movement velocity of band is low, the movement velocity of about 20m/min in the detailed disclosed Application Example in for example superincumbent table 1 and 2.
Yet when the movement velocity of band increased, elastomer material was not sufficient to finish heat exchange the duration of contact on band, thereby the temperature of elastomer material still is lower than the temperature of band.Therefore, movement velocity (corresponding to the movement velocity of industrial components) to about 150m/min, and for about 150 ℃ band initial temperature, the elastomer material part reaches about 100 ℃ top temperature, and this is corresponding to the common working temperature of most of vulcanized elastomer materials.
Can consider the variant and the different schemes of above-described method and assembly.Especially, the quantity of the supporting roll and second cooling roller, their size and their layout all only are subject to main cooling roller available free space on every side.Any combination all is possible, as long as each supporting roll is cooled off by at least one second roller.As an example, Fig. 3 illustration one with five supporting rolls 14 and four the second main cooling rollers 10 that cooling roller 16 links.
In addition, cooling roller 14 can comprise multilayered structure, and in order to implement the present invention, only outer must have top disclosed characteristic aspect elasticity and thermal capacitance.
In addition, cooling roller 16 can be replaced by other radiator cooler, and for example by the system of gas injection quenching, the part outside surface that needs only these devices and supporting roll forms suitable hot driving zone.
